Thanks Mike!I'm using the PFERD Three Square files, they are almost like using a round file. It is the only one I have used, but I'm happy with it.
Even in clean wood, it is good to touch it up after about 2 tanks. Square is much better if you keep it sharp. Remember, you now have to go from the outside in, and keep the corner of the file in the corner of the chain. Your experienced at sharpening, you will pick it up quick.
